Last year’s independence campaign sparked several incidents involving police as tensions ran high on both sides of the debate.

Labour MP Jim Murphy suspended his speaking tour of Scotland after having eggs thrown at him in the Fife town of Kirkcaldy, claiming that the Yes campaign was creating a “mob atmosphere”.

Meanwhile, the then Scottish first minister Alex Salmond said he had been involved in a “road rage” incident in which he was chased in his car by someone waving a No sign.

The door handles of a Yes shop in Penicuik, East Lothian, were smeared in excrement in August, while a pro-independence store in Edinburgh’s Newington area was daubed with Nazi slogans and the words “No Thanks”.

Following the No vote, trouble flared in Glasgow city centre when around 700 people gathered in the George Square area.

The incident, which was condemned by thousands of city residents and politicians, began after loyalists bearing Union flags clashed with pro-independence supporters.

More than 20 people were arrested following the trouble on 19 September.

It also emerged after the vote that a special police taskforce had been set up to tackle referendum-related crime during the independence campaign.
